• Glucose breakdown is therefore an oxidation-reduction reaction
Breakdown of one glucose results in 36 to 38 ATP molecules
It actually takes place in two parts of the cell
• Glycolysis occurs in the Cytoplasm
• Krebs Cycle & ETC Take place in the Mitochondria
Cellular respiration takes place in an organelle of cells called the mitochondria. Organelles are special structures within cells that carry out a specific function for the cell. The mitochondria is often referred to as the powerhouse of the cell because of being the site of cellular respiration, the process by which energy is placed into usable form for the cell, cell power or ATP. (Adenosine triphosphate)
1. One Glucose is broken down into 2 molecules of pyruvic acid.
2. Transition Reaction: Pyruvic Acid is shuttled into the mitochondria, where it is taken to a molecule called Acetyl CoA for further breakdowns. 3. The Krebs Cycle, or Citric Acid Cycle which occurs in the mitochondrial matrix. In the presence of Oxygen gas (O2), all of the hydrogen (H2) are stripped off the Acety CoA two by two, to extract the electons for making ATP.
4.Electrons from Hydrogen are carried by NADH and passed down an electron transport chain to result in the production of ATP.

Peter Mitchell won the Nobel Prize in 1978 for his work on energy production in mitochondria, called the Chemiosmotic Theory.
